For example, a positive alternating current flows through the first high-voltage winding, while a negative alternating current flows down to earth via the second high-voltage winding. If the current is only driven via a high-voltage winding, the other winding, which is not currently being flowed through by the alternating current, can be subjected to a direct current in order to saturate the core leg enclosed by it to the desired extent.
